A. In determining the passenger capacity of a school bus for purposes other than actual passenger load (e.g., vehicle classification or various billing/reimbursement models), any location in a school bus intended for securement of a wheelchair during vehicle operation shall be regarded as four designated seating positions, and each lift area shall count as four designated seating positions.

54

88. Wheelchair Lift.

A. The wheelchair lift shall be located on the right side of the bus body. Exception: The lift may be located on the left side of the bus if, and only if, the bus is only used to deliver students to the left side of one-way streets.

1. A ramp device may be used in lieu of a mechanical lift if the ramp

A readily accessible ramp may be installed for emergency exit use. If stowed in the passenger compartment, the ramp must be properly secured and placed away from general passenger contact. It must not obstruct or restrict any aisle or exit while in its stowed or deployed position.

3. All specially equipped school buses shall provide a level-change

mechanism or boarding device (e.g., lift or ramp), complying with paragraph B or C of this section, with sufficient clearances to permit a wheelchair user to reach a securement location.

deflection.)

11. Platform movement: (See 49 CFR 571.403, S6.2.3, Maximum platform acceleration.)

12. Boarding direction: The lift shall permit both inboard and

outboard facing of wheelchair and mobility aid users.

13. Use by standees: Lifts shall accommodate persons who are using walkers, crutches, canes or braces, or who otherwise have difficulty using steps. The platform may be marked to indicate a preferred standing position.

14. Handrails: (See 49 CFR 571.403, S6.4.9, Handrails.) 15. Circuit breaker: A resettable circuit breaker shall be installed

between the power source and the lift motor if electrical power is used. It shall be located as close to the power source as possible, but not within the passenger/driver compartment.

16. Excessive pressure: (See 49 CFR 571.403, S6.8, Jacking

prevention.) 17. Documentation: The following information shall be provided with

each vehicle equipped with a lift:

a. A phone number where information can be obtained about installation, repair and parts. (Detailed written instructions and parts list shall be available upon request.)

b. Detailed instructions regarding use of the lift shall be

readily visible when the lift door is open, including a

56

diagram showing the proper placement and positions of wheelchair/mobility aids on the lift.

18. Training materials: The lift manufacturer shall make training

materials available to ensure the proper use and maintenance of the lift. These may include instructional videos, classroom curriculum, system test results or other related materials.

19. Identification and certification: Each lift shall be permanently and

legibly marked or shall incorporate a non-removable label or tag that states it conforms to all applicable requirements of the current National School Transportation Specifications and Procedures. In addition and upon request of the original titled purchaser, the lift manufacturer or an authorized representative shall provide a notarized Certificate of Conformance, either original or photocopied, which states that the lift system meets all the applicable requirements of the current National School Transportation Specifications and Procedures.

89. Ramps.

A. When a power lift system is not adequate to load and unload students having special and unique needs, a ramp device may be installed. 1. If a ramp is used, it shall be of sufficient strength and rigidity to

support the special device, occupant, and attendants. It shall be equipped with a protective flange on each longitudinal side to keep special device on the ramp.

2. Floor of ramp shall be of nonskid construction.

3. Ramp shall be of weight and design, and equipped with handles, to

permit one person to put ramp in place and return it to its storage place.

90. Regular Service Entrance.

B. The opening to accommodate the special service entrance shall be at any

convenient point on the right (curb side) of the bus and far enough to the rear to prevent the doors, when open, from obstructing the right front regular service door (excluding a regular front service door lift).

C. The opening shall not extend below the floor level. Outboard type lifts

shall be used.

D. The opening, with doors open, shall be of sufficient width to allow the passage of wheelchairs. The minimum clear opening through the door and the lift mechanism shall be 30 inches in width.
